Antidepressant-Like Effect of Different Estrogenic Compounds in the Forced Swimming Test
TLDR
Both E2 and EE2 produced a decrease in immobility and an increase in swimming, suggesting an antidepressant-like action, and DES did not affect the responses in this animal model of depression at any dose tested.
Stimulation of 5-HT1A and 5-HT1B receptors in brain regions and its effects on male rat sexual behaviour.
TLDR
The results would suggest that at least some of the 5-HT1A receptors involved in the facilitation of male sexual behaviour are located postsynaptically in limbic brain areas that regulate maleSexual behaviour.
Interaction between estrogens and antidepressants in the forced swimming test in rats
TLDR
In the FST estrogens were able to facilitate the action of two different kinds of antidepressants; however, these effects were dependent on the type of estrogen used.
Sex differences in the distribution of androgen receptors in the human hypothalamus
TLDR
The present results suggest the participation of androgens in the regulation of various hypothalamic processes that are sexually dimorphic in men and women using the antibody PG21.
Anxiolytic-like actions of testosterone in the burying behavior test: role of androgen and GABA-benzodiazepine receptors
TLDR
Neither repeated- nor single-treatment with 3alpha-androstanediol nor androsterone produced a reduction of anxiety-like behavior, and the possible participation of androgen or GABA(A)-benzodiazepine receptors in the anxiolytic-like effect of TP was analyzed.
Participation of the 5-HT1A Receptor in the Antidepressant-Like Effect of Estrogens in the Forced Swimming Test
TLDR
The results support the notion that the 5-HT1A receptor is one of the mediators of the antidepressant-like action of E2, and could indirectly contribute to the one induced by EE2.
Role of maternal behavior on aggression, fear and anxiety
TLDR
The results suggest that aggression and reduced fear, but not anxiolysis, partially depend on the development of maternal behavior.
Aging increases the susceptibility to develop anhedonia in male rats
TLDR
It is suggested that the higher susceptibility to develop anhedonia in male rats could be associated to neuroendocrine changes consequent to aging.
Flumazenil blocks the anxiolytic action of allopregnanolone.
TLDR
The results indicate that the anxiolytic actions of neurosteroids are most likely mediated via the stimulation of GABAA receptors, and that the effect of these treatments was selective on experimental anxiety.
Estrogens participate in the antidepressant-like effect of desipramine and fluoxetine in male rats
TLDR
Estrogens participate in the antidepressant-like effect of DMI and FLX in the FST, and 17beta-estradiol (E2) modifies the F ST and interacts with the antidepressants in orchidectomized (Orx) males.
